Abstract
The invention relates to a self-closing sealing choke plug, which comprises a sealing choke plug, a connecting cylinder fixed by a round nut, with one end sleeved in the sealing choke plug, and a pressure sensor mounting groove arranged in the connecting cylinder, wherein the sealing choke plug is provided with a sealing choke plug screw thread connected with a high-pressure closed container; the connecting cylinder is provided with a connecting cylinder sealing inclined plane; and the sealing choke plug is provided with a sealing choke plug inclined plane by correspondingly contacting with the connecting cylinder sealing inclined plane. By adopting the self-closing sealing choke plug, the higher the pressure of the gas in the high-pressure closed container is, the closer the contact of the connecting cylinder sealing inclined plane and the sealing choke plug inclined plane is, and the sealing performance is better. The self-closing sealing choke plug is used on a closed container the volume of which is 700mL as traditionally rigidly sealed in a closed container the volume of which is 200ml, the normal detection of pressure can be ensured. The installation and the operation are more convenient and the time and labor are saved by adopting the self-closing sealing choke plug.
Description
Technical field
The present invention relates to a kind of Self-closing sealing choke plug.
Background technique
What the sealing of current closed pressure vessel adopted is gun iron link structure, directly sealing is threaded connection with the sealing plug of detected pressures sensor and pressurized container, i.e. steel sealing, its advantage is that structure is simple, shortcoming be assemble and unloading time need larger strength, assembling and unloading inconvenient, especially the volume of closed pressure vessel and internal pressure larger time, adopt this steel sealing effect not obtain Reliable guarantee, easily cause danger.
Summary of the invention
Technical problem to be solved by this invention is to provide that a kind of high-pressure closed vessel pressure is larger, and seal action is better, and fitting operation Self-closing sealing choke plug eaily.
The present invention adopts following technological scheme:
The present invention includes sealing plug, one end is sleeved on the connecting cylinder fixed by round nut in sealing plug and the pressure transducer mounting groove be arranged in connecting cylinder, described sealing plug is provided with the sealing plug screw thread be connected with high-pressure closed vessel, connecting cylinder is provided with connecting cylinder sealing inclined-plane, and corresponding and connecting cylinder seals inclined-plane and contacts be provided with sealing plug inclined-plane on sealing plug.
Beneficial effect of the present invention: when in high-pressure closed vessel, gas pressure is larger, connecting cylinder sealing inclined-plane and sealing plug contact of incline plane tightr, sealability is also better, the present invention use on the seal container of 700mL volume be sealed in 200mL volume with traditional rigidity formula seal container on use the same, can ensure that pressure normally detects (and the seal container adopting traditional rigidity formula to be sealed in 700mL volume uses can not obtain Reliable guarantee, easily cause danger), adopt fitting operation of the present invention more convenient, time saving and energy saving.

Embodiment
Attachedly Figure 1 shows that one embodiment of the present of invention, the present invention includes a sealing plug 6, connecting cylinder 1 and round nut 5.Sealing plug 6 is fixed on high-pressure closed vessel 8 by sealing plug screw thread 7, pressure transducer is arranged on the pressure transducer mounting groove 4 of connecting cylinder 1, the transfer wire of pressure transducer is drawn outside high-pressure closed vessel 8 by sealing plug 6 one end, and connecting cylinder 1 is fixed by round nut 5 and sealing plug 6.Corresponding with the connecting cylinder sealing position, inclined-plane 2 be arranged on outside connecting cylinder 1, sealing plug 6 is provided with sealing plug inclined-plane 3, connecting cylinder sealing inclined-plane 2 and sealing plug inclined-plane 3 contact, when in high-pressure closed vessel 8, gas pressure is larger, connecting cylinder sealing inclined-plane 2 contacts tightr with sealing plug inclined-plane 3, and sealability is also better.Fitting operation of the present invention is more convenient, and more laborsaving, and pressure is larger, and seal action is better.
Self-closing sealing choke plug of the present invention is for the high-temperature gas pressure test generated of burning under airtight condition, and gas pressure declines along with the reduction of temperature, and therefore its sealability adopts comparative test to test.Under identical loading density (filling quality/seal container volume), the gas pressure-time graph generated after test burning, Fig. 3-Fig. 8 is respectively 0.24gcm
-3, 0.20gcm
-3and 0.12gcm
-3under loading density, the test result of the seal container (adopt self-closing of the present invention to seal, see Fig. 3,5,7) of 700mL volume and the seal container (adopt existing rigidity formula to seal, see Fig. 4,6,8) of 200mL volume compares.Test result shows the present invention and traditional steel sealing Method compare, the present invention use on the seal container of 700mL volume be sealed in 200mL volume with traditional rigidity formula seal container on use the same, can ensure that pressure normally detects (and the seal container adopting traditional rigidity formula to be sealed in 700mL volume uses can not obtain Reliable guarantee, easily cause danger).
